Bath, Ohio Application June 14, 1950, Serial No. 167,996 3 Claims. (Cl.160-90 This invention relates to an improvement in combination screenand storm doors, and more particularly to a self-storing door, havingadvantageous safety features for permanently hung combination storm andscreen doors.

Heretofore, the most common combination storm and screen doors have beenthose in which removable screened and glazed sashes have beeninterchangeably mounted. While such combination doors are far moreconvenient to handle and permit a more simple conversion from a screenedto storm closure than the prior practice of hanging a storm door on thehinges of a screen door, such removable sash doors still presented theinconvenience of having to store relatively heavy sash when such sash isnot in use. The interchanging of stored sash at the change in seasons isoften a nuisance and the problem of storing sash presents a real problemin smaller modern homes where storage space is at a premium.

To overcome the nuisance of interchangeable sash doors, recent effortshave been made to market so-called self-storing doors which'follow theconstruction of the so-called self-storing storm windows by providingthree sashes slidable vertically in the door, one sash being screenedand the other two being glazed. In such prior art doors, the two glazedsashes are manipulated as double hung glazed window sash so that, withone glazed sash in the upper half of the sash opening and the other inthe lower half, the door will provide glazed storm protection; with bothglazed sashes positioned in onehalf of the sash opening, the screenedsash may he slid into the other half to provide a screened opening. Suchself-storing combination doors have not been widely accepted. With thelightness of construction required in a door, the sashes tendto cock andjam, the users frequent reaction being that it would be easier to revertto the interchangeable sash employed in the earlier combination doors.Further, the vertically slidable sashes, if hung securely enough to berelatively free of rattles, are often relatively difficult to remove forcleaning. A serious objection, also, is thatwith only an upper or lowerhalf of the sash opening being available for the screened sash, poorventilation is obtained in the summer time. Still another objection tothe above described prior art self-storing doors is that a horizontallintel or sill of a sash at the mid-point of the sash opening falls atthe eye-level of many users and is unattractive to nearly all users. Andfinally, the latches secure enough to hold a raised sash againstslamming are nearly always too secure for convenient operation of thesashes. Some efforts have been made to increase the area of the sashopening available for screening by having all or a part of the glazedsashes disappear into a panel below the sash opening, but this remedyraises a further objection: it eliminates the area available for a mailslot and such a panel well traps rain and dirt which soil the glazedsash and promote rusting or rotting of the door and sash frames.

It is an object of this invention to provide a self-storing combinationstorm and screen door which overcomes the several disadvantages o fprior art doors, as discussed above, and, in addition, provides a safetyfeature which has proved very desirable to users, particularlyhousewives, which has not been available in combination doors heretoforeavailable. A door made according to our invention is provided with asash opening which is divided vertically. On one side of the opening isa relatively fixed but removable glazed sash and on the other side theinside of the doors.

line 4 -4 of r 2,702,595 l ate ed r b zz, 1955 is a relatively fixed butremovable screened sash Behind these two sashes is a third glazed sashwhichhas a width equal to approximately one-half the horizontal width ofthe sash opening andis freely slidable across theent'ire width of thesash opening in the door. In either winter'or summer, the housewife isable to stand out of the draft hehindthe g'l'a ze'd sash to talk topersons through the screened opening; such persons maybe strangers towhom the housewife would hesitate to speak in the winter hecause'ofthenecessity of opening a storm door and inthe summer because ofthe fearthat the screening could be easily cut. Even the n'iost titnid housewife'feels that she could slam the horizontally sliding glazed sash acrossthe screened opening before a substantial cut could be made in the sceened opening. Many housewives appreciate the sliding glazed sashbecause it can be quiekty closed and, thereby, provides a means forquicklyjc'ut'tirig off an undesired conversation through the screenedopening.

Another advantage of our door is that the several sashes are readilyremovable 'forclea'ning, but onlyf'rom A Other and further objects andadvantages of our invention are disclosed in the followingspecification, elaims, and dra'wings, in which: s

As shown in the drawings, such adoor is comprised ofajframe 10 .having'sill, jamb, and lintel elements 11, 12, and 13defining the sash opening in which the sashes are mounted. Between thesill elementll and the sill 'of the'frame10 is a fixed panel 14.proyided with a suitable ma'ilor parcelslot 15, which latter may be ofany conventional or convenient construction. I n

Three sashes are mounted in the sash opening of the d'oor a'n outerglazed sash 30, an outer screened. sash 40, and an inner sliding sash50. The frames of the several sashes are of overall box channelconstruction provided with suitable grooves 'tofreceive the glass panesor screening fand the suitable lockingficlips therefor; 'additionalchannels are provided to receive felt rattle strips located to preventthe sashes from rattling against each other. One of the .jambs of thesash 50 is provided with a suitable handle 51. For purposes of thefollowing description, adjacentja'rnbs of the outer sashes 30 and 40 aredesignated as 31 and 41 and the remote jambs are designated as 32 and42', respectively (see Figs. 6 and 7).

As best shown i'nsection in Figs. 3 and 4, the sill element 11 is 'of anoverall bo'x section, the upper side of which is configured to providean inner sliding sash flange 16, and, falling outwardly to the weatherside of thedoor, a sliding sash track 17 and a drain eave 18. Extendinghorizontally betweenthe jambs of the frame 10 is an angle memberconstituting a. I( l.ll1'1 teI:-Sill 1'9 pace ab g h d a ne v .8. h i di qnt le m of the counter-sill 19 being spaced below the track 17 andvertical element extending upwardly to provide, in cooperation with theshoulder of the track 17, a channel for receiving the outer glazed sash30 and the screened sash 40. As is evident from Figs. 3 and 4, any rainwhich might splash through the screened sash 40 or drain onto thecounter-sill 19 from the weather side of the glazed sash 30 may drainout to the weather side of the door over the drain eave 18.

As also shown in Figs. 3 and 4, the lintel element 13 is provided withan outer depending flange 21 and an inner depending flange 22 to definean upper channel into which the lintels of all the sashes are received.As shown in the drawings, sufiicient clear space is provided above thesashes so that, when any one sash is resting on the track 17, it may belifted into the channel 20 a suflicient distance to permit the sill ofthe sash to be swung inwardly over the flange 16. When clear of theflange 16, the sash, at a slight angle to the vertical, may then bedropped out of the channel 20 and, thereby, removed from the door. Asshown, each of the channel flanges 21 and 22 are lined with felt pads toprevent the sashes from rattling in the channel.

To secure the outside jambs of the outer glazed sash 30 and the screenedsash 40, the sash-opening jamb elements 12 (see Fig. 6) are providedwith flanges 23 against which the remote sash jambs are engaged when theouter sashes are dropped to their mounted position in the sill channelprovided by the counter-sill 19. When mounted, the remote jambs of theouter sashes fit tightly against the jamb elements 12 and their flanges23, the adjacent jambs 31 and 41 of these sashes abutting. It is to benoted that the adjacent jamb 31 of the glazed sash 30 is provided with abattan flange 33, which seals the vertical central joint between theadjacent jambs 31 and 41.

As also shown in Fig. 6, the inner sliding sash 50 is slightly widerthan either of the outer sashes. Thus, outward movement of the outersashes 30 and 40 being prevented by the flanges 21, 23, and counter-sill19, inward movement of the adjacent jamb of the sashes will be preventedby the inner sliding sash 50, which is restrained by the track flange 16and lintel flange 22. This means, however, that with the inner sash slidto one side, behind one of the sashes 30 or 40, the other sash (glazedsash 30 in Fig. 6) could be raised from the outside, and, when raisedabove the flange 16, its outer jamb 32 could be pushed inwardly, thesash 30 pivoting about its adjacent jamb 31. To prevent such inwardmovement of the remote jambs, the remote jambs carry pins 25, preferablyequally spaced from the tops and bottoms of the jambs (to permit glazedand screened sashes to be mounted in either side of the sash opening byturning the sashes end for end). The pins are received in vertical slots26 permitting the sashes to be raised up to the level of the track 17but preventing the remote jambs 31 and 41 from being pushed inwardly.

Although the sashes may not be removed from the outside, they arereadily removed from the inside, the inner sliding sash 50 being the keyto the locking of the sashes and 40. To remove the sash 50, it is simplylifted into the channel 20 and over the flange 16, as described above.With the sash 50 removed, the screened sash 40 is then lifted above thelevel of the track 17 and pivoted about its remote jamb 42 until itsinner jamb 41 is on the track 17. The sash 40 is then slid on the track17 until the pins 25 are clear of the slots 26. The sash 40 is thenremoved in the same manner as was the sash 50. With the sashes 5'0 and40 removed, sash 30 may be removed in the same manner as was sash 40.After cleaning, or repairing, the sashes 30, 40, and 50 may be replacedin order.

A somewhat sturdier means of preventing inward and outward movement ofthe remote jambs of sashes 30 and 40 while sash 50 is in place is shownin Fig. 7. In this embodiment, no slots 26 or pins 25 are employed.Instead jamb elements 112 replace the jamb 12. The inner sides of thejamb elements 112 are stepped to provide vertical channels 126 whichreceive the remote jambs 32 and 42 when the sashes 30 and 40 areinserted and the adjacent jambs 31 and 41 are abutted. The sashes areremoved and reinserted with the same movements and order as described inconnection with the embodiment in Figs. 1 to 6.

A still simpler but less convenient means for securing the remote jambsof the sashes 30 and 40 are shown in Figs. 8 and 9. In this embodiment,the jamb elements 212 are similar in section to the elements 12, but theflanges 223 are drilled to receive self-tapping screws 225 which arethreaded into the remote jambs 32 and 42. Aside from cheapness, the onlyadvantage of the embodiment shown in Figs. 8 and 9, and it is aquestionable advantage, is that all the sashes 30, 40 and 50 may beremoved, the sash-opening then being closed by a single screened sash(not shown) to provide a full-screened sash opening or by a solid sheetof plywood (not shown) for boarding up the doors of temporaryresidences. Except where these last-mentioned features are insistedupon, the modification shown in Figs. 8 and 9 is not generallyrecommended.

From the foregoing, it is apparent that our invention is not limited toany one specific embodiment but may be modified by those skilled in theart without departing from the spirit and scope of the invention asdefined in the following claims.

What is claimed is:

1. In a self-storing combination screen and storm door, lintel, jamb andsill elements defining a sash opening, said opening comprising a majorportion of the vertical area of the door, said sill element comprising atrack flange, a track below said track flange and a sill channel locatedbelow and outwardly of said track, said lintel element having an outerflange and an inner flange, respectively coplanar with the outer edge ofsaid sill channel and said track flange, to define a lintel channel, anouter glazed sash resting in said sill channel and extending into saidlintel channel, said outer glazed sash being comprised of upper andlower frame members and adjacent and remote jamb members, said outerglazed sash extending to a mid-point between said jamb elements whensaid remote jamb member is fitted against a jamb element, a screenedsash comprised of an upper member and a lower member and remote andadjacent jamb members, said screened sash extending from said sillchannel into said lintel channel, its remote jamb member fitting againsta jamb element and its adjacent jamb element abutting the adjacent jambelement, whereby said screened sash closes the balance of the sashopening partly closed by said outer glazed sash, an inner glazed sashmounted on said track and extending vertically into said lintel channel,said inner glazed sash being slidable from a position behind said outerglazed sash to a position behind said screened sash, said inner glazedsash having a width suflicient to close the screened opening in saidscreened sash when slid therebehind, and, when slid behind said outerglazed sash, sufficient to extend over the joint between said adjacentjambs but insulficient to extend appreciably over said screened opening,and said lintel channel being deep enough to permit any of said sashesto be lifted over said track flange while the upper portion thereof isin said lintel channel.

2. A door as defined in claim 1 in which said sill channel is comprisedof a counter sill raised above said sill element to provide a drainpassage toward the outside of said door.
